摘要

自计算机断层扫描问世以来,它已经走过了漫长的道路。它不再仅仅是一种用于临床诊断的方法,而是在古生物学家中越来越受欢迎,因为它可以用来分析化石遗骸的外部和内部结构,比如小昆虫、蜗牛壳和植物遗骸。本研究描述了利用微ct技术对晚白垩世和全新世早期的绿藻螺纹石进行无损分析,从样品制备(嵌入、固定)到图像的可视化和评估。除了这种非破坏性检查外,我们还希望测试计算机断层扫描是否可以用于检查旋螺仪。我们的初步结果表明,微ct技术值得进一步研究。它已经被证明可以在3D中可视化样本,旋转它们,并从不同的方向观察它们。通过使用适当的参数,我们还能够观察到特征遗骸部分之间的密度差异,并研究这些特征的几个重要定义特征。

Methodological add-ons to a non-destructive, micro-CT-based taxonomic/morphometric analysis of characean remains
Abstract Ever since its introduction, computed tomography has come a long way. No longer is it merely a method that is used in clinical diagnostics, but it is becoming more and more popular among palaeontologists because it can be used to analyse both external and internal structures of fossil remains, such as small insects, snail shells and plant remains. The present study describes non-destructive analyses of Late Cretaceous and early Holocene charophyte gyrogonites by using the micro-CT technique, from sample preparation (embedding, fixing) to visualisation and assessment of images obtained. In addition to this non-destructive examination, we wished to test whether or not computed tomography could be used to examine the gyrogonites. Our preliminary results have made it clear that the micro-CT technique is worth employing for further research. It has proved possible to visualise the samples in 3D, rotate them, and observe them from different directions. By using the appropriate parameters, we have also been able to observe density differences between parts of characean remains and to study several important defining features of these.
